Mode decoupling controller for feedback model updating

Mode decoupling controller for feedback model updating

引用

2004 ASME International Mechanical engineering Congress and Exposition, IMECE

作者： Jung, Hnsang Park, Youngjin Park, K.C. System Dynamics and Applied Control Laboratory Department of Mechanical Engineering Korea Advanced Institute of Science and Technology Daejon 305-701 Korea Republic of Center for Aerospace Structures Department of Aerospace Engineering University of Colorado Boulder United States

A novel concept of feedback loop design for modal test and model updating is proposed. This method uses the closed-loop frequency information for parameter modifications to overcome the problems associated with the conventional methods employing the modal sensitivity matrix. To obtain new modal information from the closed-loop system, controllers should be effective in changing modal data while guaranteeing the stability of the closed-loop system. The present paper proposes a mode-decoupling controller that can alter a target mode while guaranteeing the stability of the closed-loop, and that can be constructed by using the measured open-loop mode shapes. A simulation based on time domain input/output data is performed to evaluate the feasibility of the proposed control method, which is subsequently corroborated via experiments. Experimental data obtained on a beam via the proposed mode-decoupling controller have been applied to estimate thicknesses of a beam. The results show that the proposed approach outperforms conventional methods with a far less number of data set for the estimation of system parameters. © 2004 by ASME.

作者： K. Kiguchi T. Fukuda Department of Advanced System Control Engineering Saga University Saga Japan Department of Micro System Engineering University of Nagoya Nagoya Japan

We have been developing exoskeleton systems to assist the motion of physically weak persons such as elderly, disabled, and injured persons. The proposed exoskeletons are controlled basically based on the electromyogram (EMG) signals. Even though the EMG signals contain very important information, however, it is not very easy to predict the user's upper-limb motion (elbow and shoulder motion) based on the EMG signals in real-time because of the difficulty in using the EMG signals as the controller input signals. In this paper, we propose a control method for a 3DOF exoskeleton system for human upper-limb motion assist considering the effect of bi-articular muscles.

作者： N. Bigdeli M. Haeri Advanced Control System Laboratory Electrical Engineering Department Sharif University of Technology Tehran Iran

Ultrasonic motors (USM) possess heavy nonlinear and load dependent characteristics of ultrasonic motors (USM) such as dead-zone and saturation reverse effects, which vary with driving conditions. In this paper, behaviour of an ultrasonic motor is modelled using Hammerstein model structure and experimental measurements. Simulation results show the good matching between the developed model and experimental measurements.

Ultrasonic motors (USM) possess heavy nonlinear, and load dependent characteristics such as dead-zone and saturation reverse effects, which vary with driving conditions. These properties have made the position/velocity control of USM a difficult and challenging task. In this paper, a generalized model predictive (GPC) controller for precise USM position control is suggested. Simulation results indicate improved performance of the motor for both set point tracking and disturbance rejection. Since the motor and the controller both are of type one, the applied saturation would cause in wind up phenomenon. This drawback is removed by implementing the Quadratic GPC controller.

American control Conference (ACC)

作者： M. Haeri A.H.M. Rad Electrical Engineering Department Advanced Control System Laboratory Sharif University of Technology Tehran Iran Electrical Engineering Advanced Control Systems Laboratory Sharif University of Technology Iran

In this paper, the TCP retransmission timer adjustment mechanism is approached from the system's theoretic point of view. TCP uses a simple recursive system identification algorithm to capture both time variant and time invariant Internet behavior and provides a dynamic round-trip time (RTT) predictor. Based on real Internet data collection, it is observed that when the retransmission timer is adjusted by using the proposed predictor instead of the traditional RTT estimator, its performance increases significantly.

This paper presents an exoskeleton for the assist of forearm motion (elbow flexion-extension and forearm pronationsupination motion) in daily activity and rehabilitation. The exoskeleton is controlled based on the activation patterns of the electromyogram (EMG) signals of the patient's muscles, which directly reflects the motion intention of the patient, in order to realize natural motion assist The sophisticated real-time neurofuzzy control method, in which the effect of a muscle common to both motions is taken into account, is proposed. The proposed control method enables the cooperative motion of elbow and forearm of the patient by learning the muscle activation patterns of each patient. The effectiveness of the proposed method was evaluated by experiment.

In the present study, we employed stereoscopic particle image velocimetry (SPIV) to investigate the characteristics of turbulence structures in a drag-reduced turbulent channel flow with addition of surfactant. The tested drag-reducing fluid was a CTAC (cetyltrimethyl ammonium chloride)/NaSal/Water system maintained at 25°C, having a 30-ppm concentration of CTAC. SPIV measurement was performed for a water flow (Re = 1.1×105) and a CTAC solution flow (Re = 1.5×105 with 54% drag reduction) in both the streamwise-spanwise and wall-normal-spanwise planes, respectively. A series of wall-normal vortex cores were found to align with the low-speed streaks with opposite vorticity signals at both sides of the streaks and with the vorticity decreased averagely by about one order in CTAC solution flow compared with water flow;the spanwise spacing between the low-speed streaks in the solution flow is increased by about 42%. The streamwise vorticity of the vortex cores appearing in the wall-normal-spanwise plane was also decreased by the use of additives. Copyright © 2004 by ASME.

The characteristics of vortex structures and turbulent events of drag-reducing surfactant (CTAC) solution flows in a two-dimensional channel have been studied using particle image velocimetry (PIV) to measure the instantaneous velocity fields in a streamwise-wall-normal plane. Through visualizing the instantaneous velocity field, contour maps of the swirling strength and instantaneous value of uv, the characteristic angle of vortex packets was quantified, and it was shown that the drag-reducing CTAC additive reduced both the strength and frequency of turbulent bursts near the wall, and that the characteristics of vortex structures and bursts were not only dependent on drag-reduction level but also on concentration of additive. Based on the quantified parameters characterizing turbulent events in a wall-bounded turbulent flow, a model of turbulent contribution to the friction factor, f T, was proposed. It was obtained that fT was linearly proportional to the product of frequency and strength of turbulent events. Copyright © 2004 by ASME.

Visual cues that are relevant to safe car driving are generally not supported by redundant non-visual cues, resulting in increased accident risk when visual attention is misallocated. Haptic gas pedal feedback, also referred to as longitudinal impedance, may assist drivers in proper and timely reallocation of their visual attention. A solution is presented for translating the relevant two-dimensional situation in front of the driver into a total hazard level from which gas pedal feedback force is calculated. Car driving simulations, that include a radar-like sensor model and a human driver model, were performed for several highway maneuvers. The simulations indicated that the calculated gas pedal feedback force is a weighted mix of hazard-defining variables depending on the positions of the lead vehicles in front of the own vehicle

SICE Annual Conference

作者： K. Izumi K. Watanabe Y. Koga K. Kiguchi Department of Advanced System and Control Engineering Saga University Saga Japan

The inverse model of a nonholonomic system is not unique. Such an inverse model changes depending on initial conditions and desired values. In this paper, a kind of internal model control (IMC) using feedback error learning is discussed for the tracking control of nonholonomic mobile robots. The present method is different from a conventional IMC whose control system consists of an inverse model, a direct model and a filter. The present disturbance rejection method need not use a direct model, where the remaining two elements are composed of the same inverse model based on neural networks.
